Kita-ayase Station (北綾瀬)
Kita-ayase existed as railway infrastructure a decade before it existed as a station: from December 1969 the site was a signal point handling trains in and out of the Ayase depot. Housing spread over the fields around it, residents pressed for a stop, the ministry approved one on 1 September 1978, the name was settled that December and the station opened on 20 December 1979 — a single elevated side platform on one of the two tracks, which is all a three-car shuttle to Ayase needed.
That arrangement lasted forty years. Rebuilding from 2015 stretched the platform 135 m toward Ayase, and on 16 March 2019 ten-car Chiyoda Line trains began running through to Yoyogi-uehara, with a new south gate and exit 5 opening the same day; exit 1 and the north gate followed on 19 December 2020. Shops under the viaduct opened in 2021, and a station plaza and a sixth exit with a pedestrian deck in June 2025. C20 is one of the few Tokyo Metro terminals with no other railway at all.
Finding Kita-ayase on the signs
Every line gives the station its own letter-and-number code. You never have to read the Japanese name to find the right platform.
Station numbers at Kita-ayase
Tokyo signposts every platform, exit and train door with a letter and a two-digit number. Matching the number is faster than reading the name — and it is what you will see on the map, in announcements and on the platform edge.

Departure times come from the operators’ own GTFS timetables (ODPT GTFS Toei-Train-GTFS (version 20261009, valid 2026-03-14..2027-03-12) + TokyoMetro-Train-GTFS (version 20261008, valid 2026-09-19..2027-03-12)). Japan publishes two subway timetables: 平日 weekdays and 土休日 Saturdays, Sundays and national holidays. There is no separate Sunday timetable, and the December 30 – January 3 period runs the holiday timetable.

Transfers and connections

What is near Kita-ayase Station?
This is the eastern edge of Adachi, flat and largely built up with housing that arrived after the depot did. The station plaza opened in June 2025 gives the buses and taxis a proper forecourt, and the retail arcade under the viaduct covers the everyday shopping; Sobunuma Park is about 150 m away, a police station roughly 160 m, and a hospital and a temple within 300 m. Beyond that the draw is the depot itself, hard to miss beside the line.

Frequently asked questions
Kita-ayase opened in 1979 as a shuttle branch worked by three-car trains, and short workings to Ayase are what remains of that. Since 16 March 2019 the platform has been long enough for ten-car trains, so services are now a mix of shuttles and through trains to Yoyogi-uehara.
No. It began in December 1969 as a signal point on the approach to the Ayase depot, with no public access. The area filled with housing after the Chiyoda Line opened, local pressure produced an approval in September 1978, and passengers were first carried from 20 December 1979.
